In case playing list is selected, then system, control circuit 111 is read selected playing list information from CD.On each playing list, write information about the reproducting method of representing by type_of_presentation.In addition, write the filename of the stream file that reproduces and reproduce the zero hour, the reproduction termination moment etc. as playing list information.In addition, write the playing list label information.On the playing list label information, write the playing list number corresponding, corresponding sketch map number etc. with the moment of marking.
At first, be 0 o'clock at type_of_presentation, that is,, the action of transcriber is described to carry out the common example that is reproduced as.
Type_of_presentation is 0 o'clock, and document order specified in playitems playitem is reproduced.Specifically, system, control circuit 111 is read the information of playitems playitem foremost, reads out in the clip information file 207 that the Clip_information_file correspondence is write in the there.Secondly, with clip information the moment of IN_time that writes in the playitems playitem and OUT_time is transformed into the beginning number of packets of information and stops number.Then, read the stream file corresponding, begin to reproduce from beginning the corresponding packets of information of number with packets of information with Clip_information_file.The stream information bag that reproduces is according to the time tag that writes on the packets of information, and the timing predetermined outputs to acoustic information decoder 107 and picture information decoding device 109 from output control circuit 104.In acoustic information decoder 107, acoustic information is decoded, output to acoustic information lead-out terminal 108.Similarly, decode in 109 pairs of image informations of picture information decoding device.Output to image information lead-out terminal 110.And caption information or chart-information etc. are also decoded by predetermined decoder (not shown), with the overlapping output of image information signal.Multiple chemical control system instruction in the stream is input to system, control circuit 111 from output control circuit 104, carries out instruction interpretation.
The reproduction of above-mentioned stream file is carried out till the packets of information of the termination message Bale No. sign indicating number corresponding with OUT_time on the playitems playitem 902.In case the reproduction of the information for still picture 904 corresponding with playitems playitem 902 stops, and then similarly carries out the reproduction of next playitems playitem 903.In case the reproduction of a succession of playitems playitem of record stops on playing list 901, then returns the selection of playing list.Certainly, also can be controlled, so that the reproduction of next playing list is proceeded.
Secondly, processing is illustrated to the skip action during the renders image information.
As described above, the label information of recording played inventory in playing list 901.In the playing list label information, the corresponding moment that writes label record with playitems playitem.In playitems playitem 901 is reproduced, push next chapters and sections button of remote controller by the user, when the reproduction that begins from next chapters and sections begins, read with reproduce in the corresponding playing list label information of playitems playitem, as skip flag contrast present now again the chapter marker 901 after more retrieve.
In present embodiment, each playitems playitem is corresponding with separately chapters and sections, and the rest image mark of the information for still picture foremost of chapters and sections and chapter marker are illustrated as the mark of dual-purpose, yet, the invention is not restricted to this, can make also that image sets is corresponding with playitems playitem arbitrarily.Also can distinguish chapter marker and rest image mark.
When in the playing list label information corresponding, not having following skip flag, also can retrieve from the information of the playing list mark corresponding with following playitems playitem with the playitems playitem in the reproduction.
From the chapter marker of retrieving like this 910, obtain chapter marker by mark_time_stamp, obtain beginning information reproduction Bale No. sign indicating number from clip information after, begin the reproduction of information for still picture 905 from its packets of information.In view of the above, can be corresponding with next chapters and sections button, carry out the reproduction that begins from next chapters and sections.
Similarly, push previous chapters and sections button and carry out chapters and sections before be close to when beginning to reproduce, read the playing list label information in the reproduction, retrieve the chapters and sections skip flag more preceding than present now again.When in the playing list label information corresponding, not having previous chapters and sections skip flag, also can retrieve from the playing list label information corresponding with being close to preceding playitems playitem with the playitems playitem in the reproduction.From the skip flag of retrieving like this, in the moment by mark_time_stamp obtains skip flag, after clip information is tried to achieve the number of beginning information reproduction bag, begin the reproduction of stream file from its packets of information.In view of the above, corresponding with previous chapters and sections button, can carry out from being close to the reproduction that preceding chapters and sections begin.
Like this, it is possible beginning from the position of the playing list mark of front and back that convection current reproduces.
Secondly, the switching motion (skip etc.) of image information is described.
In information shown in Figure 9, in playing list 901, comprise 902 and 903,2 playitems playitem as playitems playitem.In case playing list 901 is reproduced, then at first the additional information 907 of the information for still picture 904 that comprises in playitems playitem 902 and acoustic information corresponding with it etc. is reproduced.Here, information for still picture 904 shows after stream reproduces at once.On the other hand, additional information 907 is the stream with predetermined length, uses the scheduled time (for example 5 seconds) to reproduce.This recovery time determines when information makes.After reproducing, playitems playitem 902 carries out the reproduction of playitems playitem 903.In playitems playitem 903, comprise 2 information for still picture 905 and 906.In addition, the additional information of acoustic information corresponding with these information for still picture etc. is 908.In case playitems playitem 903 is reproduced, then at once, information for still picture 905 is shown, only through showing information for still picture 906 after the predetermined instant.Export additional information 908 therebetween.In case the reproduction of additional information 908 stops constantly, then the reproduction of playitems playitem 903 stops.
In the reproduction of rest image 905, push next image button here,, indicate, so that when showing next information for still picture, system, control circuit is retrieved next rest image mark 911, the reproduction that begins to flow from its position from the playing list mark.Promptly; Information for still picture 906 is reproduced.Here, the additional information 908 of acoustic information etc. and multipleization of stream of rest image, in case the demonstration of information for still picture changes, then the reproduction position of additional information also changes.Therefore, additional information 908 is carried out the reproduction of additional information 908 latter halfs from being that the corresponding position of rest image mark 911 begins to reproduce with information for still picture 906.
Similarly, in the reproduction of information for still picture 905, push previous image button, indicate, so that when showing previous information for still picture, system, control circuit begins to retrieve the rest image mark 909 before being close to, the reproduction that begins to flow from its position from the playing list mark.That is, information for still picture 904 and additional information 907 are reproduced.
Like this, the user can easily change the image information of demonstration.
, on playitems playitem, can set still_flag and still_duration.This is to be used for stopping image information display at the fixed time after playitems playitem is reproduced.For example, after playitems playitem 902 is reproduced, and then when thinking only during 10 seconds, to stop image information, still_flag is set, is provided with 10 as still_duration.System, control circuit is identified in the playitems playitem 902 and is provided with still_flag after playitems playitem 902 is reproduced, and stops display action.Specifically, stop the output of acoustic information, displays image information shows regularly according to last image information former state.Secondly, in 10 seconds of a system, control circuit timing, controlled thereafter, so that move to the reproduction of next playitems playitem.In view of the above, after playitems playitem is reproduced, can only stop at any time showing.During demonstration stops, also can when pushing next image button, beginning to reproduce from next rest image mark position by the user.Still_duration is set at 0 o'clock, is controlled, stop to show up to operating by the user.By making up this processing and instruction process, can in selecting, user's menu be applied.
As shown in Figure 6, because in the message structure of the playing list information of present embodiment, each playitems playitem information had still_flag, so can carry out the last image information that just in playitems playitem, comprises that the image information after playitems playitem is reproduced stops.Thereby, after reproducing, playitems playitem carries out being necessary to be divided into when image information stops playitems playitem separately.For fear of it, also consider in playitems playitem, to write down the method for still_flag and still_duration information.
In the stream corresponding, only comprise information for still picture, do not comprise the additional information of acoustic information etc. with playing list 912.Also can similarly carry out reproduction processes or skip action in this case with playing list 901.
With the situation of information for still picture similarly, by corresponding with mark in whole I images of dynamic image data, when showing animation information, make the conversion of I image become easy as information for still picture.
More than, in second execution mode, also can easily convert next image information to even record a plurality of information for still picture, return the operation of previous image information.In addition,, also can easily convert next image information to, return the operation of previous image information showing under the situation of dynamic image data as information for still picture.
Secondly, the 3rd execution mode is illustrated.In the skip action of explanation hereto, when the demonstration of conversion information for still picture, also change the acoustic information that reproduces simultaneously., under the situation that menu is selected or as the phase of photo show under the situation of information for still picture that the scheme of not interrupting output sound information continuously is more convenient.Therefore, different with common playitems playitem as shown in figure 10, using as sub-playitems playitem record BGM acoustic information is possible also.Figure 10 represents that the information for still picture to band BGM carries out the correspondence of information under the reproduction situation.
As shown in Figure 9, when information for still picture and acoustic information etc. is carried out multipleization record, during selection converted image information by the user, also can in the image information conversion, change for the additional information of acoustic information etc.This is realizing becoming inconvenient under the such situation of menu image information faces with information for still picture.Even therefore when converted image information, should acoustic information do not interrupted yet, reproduce continuously such reproducting method correspondence.
Specifically, as shown in figure 10, in playing list, when specifying a plurality of information for still picture, as sub-playitems playitem specified voice information as common playitems playitem.In view of the above, acoustic information reproduces independently as sub-playitems playitem and information for still picture, even also can reproduce continuously acoustic information when the conversion information for still picture.
As message structure,, can represent that this playing list is the information for still picture of band BGM by specifying 1 among the type_of_presentation in PlayList information.
Secondly, expression has the information regeneration order of the BGM of Figure 10 record with acoustic information.
Under the situation that the information for still picture of being with BGM reproduces, set 1 as type_of_presentation.
In playing list 1001, comprise sub-playitems playitem 1010, also have 2 playitems playitem 1002,1003 simultaneously.Specifically, on the message structure of Fig. 6, specify stream 1011 conducts
SubPlayItem ()Here, in the stream corresponding, except image, comprise caption information or image information, control command etc., yet do not comprise acoustic information with playitems playitem.On the other hand, in the stream 1011 of sub-playitems playitem, only comprise acoustic information.
When stream 1001 reproduces, from playing list (Fig. 4), obtain the information of playitems playitem (1002 and 1003) and sub-playitems playitem 1010.
Secondly, from playitems playitem (Fig. 6), read clip information file according to Clip_information_file_name.Use this clip information file, try to achieve the stream reproduction start information Bale No. sign indicating number constantly corresponding with IN_time.In addition, read the stream file corresponding, begin output, carry out the decoding of image information from above-mentioned reproduction start information Bale No. sign indicating number with above-mentioned clip information file.Here, the stream 1004,1005,1006 that reproduces as playitems playitem does not comprise image information and caption information, acoustic information shown in as described above.Still controlled even perhaps comprise acoustic information, so that not discarded output.By such processing, carry out the reproduction of the playitems playitem in the playing list 1001.
On the other hand, in playing list 1001 middle finger stator playitems playitem 1010.If specify 1 as type_of_presentation in playing list information, then the system, control circuit in the transcriber judges that this playing list carries out is that the information for still picture of band BGM reproduces.At this moment, sub-playitems playitem is handled as the BGM acoustic information.Specifically, read in the stream 1011 corresponding, control, so that its repetition with sub-playitems playitem 1010.Certainly, also can only reproduce once by antithetical phrase playitems playitem stream, also can in playitems playitem, write down the such information of number of times of reproducing of specifying.Here, be necessary playitems playitem is reproduced and parallel the carrying out of sub-playitems playitem reproduction.At this moment, if controlled,, then can reproduce output stream simultaneously so that read both sides' stream file by multiple processing of time-division.Certainly, be ready to jumbo buffer storage, also can after all reading sub-playitems playitem, be controlled, so that output.
Secondly, under the situation of message structure shown in Figure 10, the action of the conversion of the information for still picture that passes through the user is described.
If as previously mentioned, playing list 1001 is reproduced, then to playitems playitem 1002 and 1003 sequential reproduction, show information for still picture.At this moment, also antithetical phrase playitems playitem 1010 parallel reproductions, the acoustic information in the output stream 1011.
For example, in convection current 1005 is reproduced, push next image button, under the situation of indicating next information for still picture to show by the user, system, control circuit is retrieved next rest image mark 1009 from the playitems playitem mark, begins from its position to reproduce.Therefore, the information for still picture of reproduction is converted to 1006, shows the information for still picture that wherein comprises.
On the other hand, because sub-playitems playitem 1010 continues to reproduce with the operation of being changed by user's information for still picture independently, even so under the situation of conversion by the image information reproduced from user's indication, also can not interrupt acoustic information, and convection current 1011 successively reproducings.
Under the situation of message structure shown in Figure 10,, also can after reproducing, each image information only stop at any time showing by using still_picture_flag and still_duration.If controlled in this case,, then do not interrupt acoustic information so that the sub-playitems playitem 1010 as the BGM acoustic information is exported continuously.
As shown above, in the 3rd execution mode, by with sub-playitems playitem as the BGM acoustic information, even also can export continuously under the situation of image information conversion being undertaken to acoustic information by the user.
In above-mentioned concrete example, enumerated chapter marker and 2 kinds of work examples of rest image mark as the playing list mark, and used them respectively, but be not limited thereto, can also use identical playing list mark.At this moment can to whether common dynamic image data be reproduced or information for still picture reproduced and judge, and handle.
More than, in the 3rd execution mode, recording under the situation of a plurality of information for still picture, also can be converted to next image information easily, return the operation of previous image information.Also can show information for still picture in the limit, the limit is as the continuous output sound information of BGM.
More than, according to the present invention, the conversion information for still picture is reproduced becomes possibility, in addition, can provide reproducing technology easy to use.
Can implement the present invention not breaking away under other form spirit of the present invention or principal character, the foregoing description.Therefore, the foregoing description all only is an example of the present invention in whole main points, should restrictedly not explain.Scope of the present invention is represented by the scope of claim.And, belong to this patent claim scope equalization scope distortion or the change all within the scope of the invention.
